5.4.3.5. SYNC ADC INPUT
This BNC allows you to monitor an auxiliary signal in the + 10 V range with 16-bit resolution. This signal is
monitored synchronously with the E and I channels.
5.4.3.6. DAC OUTPUT
This connection, DB9 pin or BNC with optional PMC ALG01 cable, delivers a precise DC voltage in the +
10 V range. This output can be used to control the rotation speed of rotating disk electrodes (RDEs).
CAUTION: The voltage at this connection will be random at power-on until the system fully boots (~ 1 min
after power-on). As a result, no connection should be made until system has completely booted, or in the
case of an RDE (i.e., the 616/636 systems), leave the power off on the RDE until the system is completely
booted.
5.4.3.7. E MON
This connection, DB9 pin or BNC with optional PMC ALG01 cable, outputs the analog of the reference
voltage (±10V range, 50Ω output impedance), however, the polarity at E MON is opposite that at the cell.
5.4.3.8. I MON
This connection, DB9 pin or BNC with optional PMC ALG01 cable, outputs the analog of the current with
±2V corresponding to +/- full scale current range, 50Ω output impedance.
NOTE: If the PMC-1000 channel is operating in “float” mode, then all connections to the Analog Connector
must be floating (isolated from ground) as well. If a grounded connection is made to any panel connectors
(any non-isolated connection), then the PMC-1000 system will no longer be isolated itself, and ground loops
will result in excessively noisy data.
